Extract of sample "Information and System Security"

Information and System Security Information security means protecting information and information systems from un ized access, use, disclosure,disruption, modification, or destruction. The terms information security, computer security and information assurance are frequently used interchangeably. These fields are interrelated and share the common goals of protecting the confidentiality, integrity and availability of information; however, there are some subtle differences between them. These differences lie primarily in the approach to the subject, the methodologies used, and the areas of concentration. Information security is concerned with the confidentiality, integrity and availability of data regardless of the form the data may take: electronic, print, or other forms.
The field of information security has grown and evolved significantly in recent years. As a career choice there are many ways of gaining entry into the field. It offers many areas for specialization including Information Systems Auditing, Business Continuity Planning. Information security is the ongoing process of exercising due care and due diligence to protect information, and information systems, from unauthorized access, use, disclosure, destruction, modification, or disruption. The never ending process of information security involves ongoing training, assessment, protection, monitoring & detection, incident response & repair, documentation, and review.
In recent years identity management has become increasingly important, especially in the financial services, healthcare and government industries. Why identity management has emerged as a growing business and IT priority is no mystery. Obvious drivers include the need to protect one's intellectual property, data brand value and customer loyalty from the potential damage wrought by electronically-based fraud and theft; the desire to cut technical support costs, increase productivity through self-service and enable integration across disparate platforms. Less obvious reasons, but equally important, include the challenges presented by changing environments, such as mergers, outsourcing, federated systems and global infrastructures, as well as industry and government regulations such as HIPAA, Sarbanes-Oxley and Gramm-Leach-Bliley acts.
The dictionary defines hackers as, "a talented amateur user of computers, specifically one who attempts to gain unauthorized access to files on various systems." (Webster's pg. 610) In other words, a hacker is a person who creates programs that infiltrate your PC and steal valuable information. It's hard to put a face on a criminal when he works miles away from you but is still just as effective as any other criminal. Thanks to Hollywood and the young group of kids that crowd the Internet; hackers have almost been made out to be artist-like. The movie "Hackers" make its characters seem like misunderstood geniuses looking to express themselves. The Internet community doesn't help debunk the idea when in chat rooms and message boards you'll find its contributors immortalizing them.
Hackers do more than just create programs to steal files. "Many notorious hacks were not feats of programming, but masterful psychological ploys" (TLC, 2006). Hackers play on people's fear of viruses to cause damage to their PC's. Hacker hoaxes can be just as bad as getting a virus. For example, an email in 2002 was sent out warning people about a virus that may be on their computer (TLC, 2002). The email instructed them to delete a certain file on their hard drive because of it's virus but the file was actual vital to running Windows and deleting the file would make Windows crash.
Internet security should be a high priority on every person's list that owns a computer. It makes sense since the majority of PC owners use their computer to hold valuable information, rely on it for their work, and count on it as a tool for every day life. An attack could potentially destroy your computer and all the information saved within it.
Even worse, that information could possibly be used by someone else just like a thief would steal your belongings from your home to sell. Prevention has come along way in addressing the issue of hackers but everyday hackers are coming up with new way to attack your PC. The Internet is a great thing. It's not perfect but even its imperfections shouldn't deter your desire to explore the vast wealth of information that makes up the Internet. Being aware of risks and taking steps to protect yourself will ensure that you can explore the Internet without fear.

First, as noted by Angus, the organizations that decide to implement the strictest types of security are often much less secure than...

To ensure this, adequate and effective risk management practices must be in place – that is, risk management must be effectively integrated into an organization’s existing security model, having readily available solutions for security threats and being ever vigilant for novel security threats as they develop.
The purpose of this study is to identify the role of risk management as part of the security model of modern information systems. To address this objective, the researcher primarily undertook a comprehensive review of related literature.

...1. Tena and ity were the two ways responsible for the belief that prayers works. Tena is the way that still works today among believers. On the other hand, if we suppose that the whole world consists of energy or information (which has been proved by the scientists already), and prayers, therefore, may be the way of evolving some kind of energy and communicating it to the object of prayers, then the correlation between prayers and longevity may exist. In this case we use rationalism. However, we cannot measure this influence empirically for a number of reasons, as well as cannot envisage all the variables connected with the human life. Thus, the hypothesis made by Galton was positive, logical, and even refutable, but not strictly...

Information System Security of a Company

As companies increasingly focus on making changes to their security policies and enhancing security of their electronic resources and networks by using latest technologies, there is often a ‘weak link’ that they completely ignore.

The innovation in technology has brought a lot of facilities for us. We have better ways of life and all the facilities regarding better production and domestic tasks. Such as in the industrial production we have automatic robots that are welding, packing, moving and carrying out several other development-related tasks.

International Security Studies: Examination

Globalization affects international security in the sense that problems involving terrorism, the environment, religious extremism, weapons of mass destruction, and the economic crises have become more universal and widespread in character (Ivanov “Article”).

More lives are now affected by threats to international security; these threats did not seem too ominous before the entry of globalization. Consequently, some extremists justify the use of mass weapons of destruction in order to guarantee their security. And as globalization continues to expand and to grow bigger as a phenomenon, threats to international security are...

Economic Models: The Free Market and The State Owned System

The free market concept is mainly a theoretical concept as every country, even capitalist ones place some restrictions on the ownership and exchange of commodities (Free market economy). Therefore, the term free-market economy primarily means a system where the buyers and sellers are solely responsible for the choices they make. It gives the buyers and sellers the power to do business without being afraid of any regulations and intervention by the state. Hence, a free market gives the absolute power to prices to determine the allocation and distribution of goods and services (Free Market Economy).

Global Employee Information and Consultation: Replicating the European Model

A significant step to enhancing the employees’ right to information and consultation is the establishment of the European Works Council (EWC). The EWC Directive (94/45/EC) aims to improve cooperation in transnational companies and to allow trade unions to influence, at least indirectly, the decision-making of corporations (Lockwood and Williams). It requires community-scale undertakings and community-scale groups of undertaking to create this mechanism for regular consultation of the workforce. A ‘community-scale undertaking’ is one with at least 1,000 employees within the Member States and at least 150 employees in each of at least two Member States (Lewis and Sargeant).
